Abstract: TAG ATTACHER     Abstract of the Disclosure There is disclosed a hand-held apparatus for attaching tags to merchandise.  Apparatus according to the invention uses a fastener assembly having a  plurality of fasteners.  Each fastener has a bar section and a button or head section joined by a filament section.  Each bar section is connected to a common runner or rail by a respective neck or connector.  The apparatus causes one fastener at a time to be severed from the connector at the intersection of its bar section and the respective connector.  The bar section of the severed fastener is pushed by a push rod through an elongated bore of a needle while the filament section passes along a side opening in the needle which communicates with the needle bore.  Fastener assembly advancing means includes a toothed member and a movable member.  A guide is provided for the movable member and a flexible resilient arm connected to the movable member exerts a force on the guide.  The arm enables the movable member to deflects as it moves relative to the guide.  In the illustrated embodiment the movable member takes the form of a pawl cooperable with the toothed member.  A detent member cooperates with another toothed wheel of the fastener assembly advancing means to prevent accidental movement of the other feed wheel.  The detent member has a tooth, a socket portion and an arm extending into a hole in the body.  A compression spring acts on the detent member between the socket portion and the tooth.  The end of the arm of the detent member is depressible to release the tooth of the detent member from the other toothed member.  In another embodiment, a movable member includes a pawl member and a flexible resilient arm which moves with the pawl member.  The arm is in contact with a first guide and urges the pawl member into contact with a toothed member and a second guide.  In still another embodiment, a plurality of flexible resilient arms are connected to the pawl member and are in contact with a first guide for urging the pawl member into contact with a toothed member and a second guide.  In yet another embodiment, a pawl member includes a first flexible resilient arm having a tooth at its free end portion cooperable with the toothed member and a second flexible resilient arm connected to the pawl member and movable with the pawl member.          In another embodiment, relatively movable slides are coupled by a lost-motion connection.  A one-piece pawl coupled to one of the slides has a tooth cooperable with the toothed member and a flexible resilient arm cooperable with a guide for urging the tooth into cooperation with the toothed member.

Abstract: ROTARY PISTON ENGINE                 ABSTRACT OF THE DISCLOSURE         An engine having a drive shaft secured to a rotary piston mounted within a casing.  An intake-compression chamber between the casing and piston is supplied with fuel through an intake port.  The rotary piston has an annular expansion-exhaust chamber and an exhaust port on the casing communicates with that chamber.  A drive flap pivotally mounted on the piston swings into and out of the expansion-exhaust chamber between open and closed positions as the piston rotates, the flap thus forming a movable pressure barrier extending across the expansion-exhaust chamber.  The piston has a plurality of turbine slots circumferentially spaced apart in a direction extending away from the direc-tion of rotation of the piston so as to sweep successively across the combustion chamber and connect said chamber to the expansion-exhaust chamber.  Also, a cam member is carried by the casing to project into the expansion-exhaust chamber, the member being positioned to control movement of the drive flap between the open and closed positions in timed relation to ignition of a combustible mixture within the combustion chamber.  The engine produces power at high rotational speeds which are possible because of the absence of oscillating masses which must be accelerated and retarded as is the case in a conventional piston engine.

Abstract: Abstract of the Disclosure This invention is concerned with hydrated glass articles having base compositions within the Na2O and/or K2O-ZnO-Al2O3-SiO2-Cl field and having at least a surface layer thereon containing Ag-AgCl crystals which impart photo-anisotropic effects to the glass articles.  Silver ions are introduced into the surface layer through a solution ion exchange process with sodium and/or potassium ions of the parent glass.  The silver remains in the ionic state until exposure to ultraviolet radiation which results in the development of silver-containing aggregates, i.e., Ag-AgCl, via a photolytic reaction.  The aggregates contribute to photo-anisotropic absorption bands which are centered around 340 nm and 700 nm.  Polarization of the photo-dichroic and photo-birefringent effects of the inventive products can be altered reversibly between two arbitrary directions without fatigue.  The photo-anisotropic image can be read cyclically essentially indefinitely without destruction.  The product of the invention is eminently suitable as a photosensitive medium for storing optical information.

Abstract: APPLICATION FOR CANADIAN LETTERS PATENT     INVENTOR FRANK FIEDLER, JR.     TITLE SAFETY SHUT-OFF VALVE     ABSTRACT OF THE DISCLOSURE    The invention is a pressure responsive shut-off valve in-cluding a valve housing that defines a fluid inlet and a fluid outlet separated by a valve seat.  A valve closure accommodated by the valve seat moves between open and closed positions to control fluid flow between the inlet and outlet.  Controlling the valve is a valve operator including a pressure responsive piston that moves between a set position in which the valve closure is separated from the valve seat and a release position in which the closure is seated on the seat to prevent fluid flow between the inlet and outlet.  Retaining the piston is a cylinder body that defines an activating volume communicating with the inlet and establishing on one face of the piston a fluid pressure forcing the piston toward its release position, and a reference volume communicating with the inlet and establishing on the oppo-site face of the piston a reference volume.  An internal seal isolates the inlet from the reference volume with the piston in its set position while allowing fluid communication therebetween with the piston in its release position.  Maintaining the piston in the set position is a latching mechanism that, after activation of the piston to its release position by excessive pressure, can be restored by a manual reset.

Abstract: PROCESS FOR TREATING CYANIDE AND CYANATE         CONTAINING WASTEWATERS                   ABSTRACT OF THE DISCLOSURE        A process for treating a cyanide and cyanate-containing aqueous influent such as a wastewater stream is provided.  A two-stage method is included for destroying a cyanide-containing in-fluent which comprises;         (a) introducing said cyanide-containing influent into a first ozone-contacting zone;         (b) contacting said influent in said first zone with a second ozone-containing gas, at least a portion of said second ozone-containing gas comprising a first ozone-depleted gas with-drawn from a second contact zone to form a first cyanide-depleted effluent and a second ozone-depleted gas;         (c) introducing said first oyanide-depleted effluent into a second ozone-contacting zone;         (d) contacting said effluent in said second zone with a first ozone-containing gas to form a second cyanide-depleted effluent and a first ozone-depleted gas;         (e) withdrawing said first ozone-depleted gas from said second contact zone; and (f) withdrawing said second cyanide-depleted effluent from said second zone.       A single stage method is also provided in this invention. Both single stage and double stage embodiments employ a turbine-gas injector in each ozone-contacting zone  to accomplish a high mass transfer of the ozone-containing gas to the influent.   In both the single stage and double stage method, the cyanide-depleted effluents may be recycled to the aqueous influent stream prior to its introduction to either the first or second ozone-contacting zone or to the contacting zones themselves to destroy cyanides and cyanates in these effluents.  This destruction is accomplished by allowing residual ozone or other oxidizing species in the recycled effluent to react with the cyanide/cyanate species and reducing influent concentrations by diluting the influent entering the contacting zones while at the same time obtaining lower ozone-containing gas to liquid (G/L) ratios.       In a further embodiment of this invention a method for treating a cyanate-containing influent formed by oxidizing cyanide by any of the above described methods is provided which comprises further multiple ozone-treatment stages.

Abstract: A B S T R A C T     The invention relates to a plate heat exchanger, which com-prises a plurality of plates located to the side of each other and consisting each of two sheets facing toward each other, which sheets are formed with longitudinal valleys, which facing toward each other form passages between the sheets when the sheets abut each other. The object of the invention is to pro-vide a plate heat exchanger with straight unobstructed passages in order to reduce the problem of clogging and to facilitate cleaning. Between adjacent passages there must be free flow so that washing can be carried out even when a single passage should have been clogged. A further advantage is that the sheets can be formed in press tools without risk of fracture indica-tions to arise. The invention implies that the valleys (5) are formed with grooves (19) transverse to the longitudinal direc-tion of the valley and extending continuously from one outer-most located valley to the other outermost located valley.
